That might be a strong motivator to scan all those classic Sam's Photofacts to digital .. silverfish do not eat metal .. unless someone has already digitized the entire Sam's collection and is sharing it with the world
9:28 YESSSS. Education! I and many others appreciate the fact that you are not just a parts swapper!!! That takes a lot of intelligence and patience! GOOD ON YA!! Love this channel!
I'm A TV tech with 40 yrs. experience who love repairing vintage equipment but damn, once I looked inside that toilet, it would have gone straight to the curb.
My father bought a Truetone tv brand new from Western Auto, it never worked right. It was in for repairs several times and one Saturday morning it started smoking, he grabbed it and threw it out the door.
The coil is a "Universal" or "diamond" wind pattern. Another similar pattern is the honeycomb which is a coarser winding. I'm putting a machine together to wind these actually. There are several RU-vid videos showing home-made winders and the grandfather of all home winders is the David Gingery design (Book). The pattern is used to minimize self capacitance which occurs when the windings are tightly wound next to each other.
I have an idea that this set was made by Sharp (I know that they built sets for WA in the '70's) and, from my experience, Sharp sets had a reputation for having bad flyback transformers. I had a friend, who fixed Truetone TV's, and he once told me that the Sharp-made B&W sets from the '70's ate flybacks.
This set definitely looks more like a Toshiba than a sharp. shango did a video a while back on a similar set that was made by Toshiba ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE--Esmvx9vZ9k.html
Yeah it has been awhile since I saw a rat nest made out of filthy wool insulation that big .. I was screaming at the screen .. CLEAR IT OUT OF THE WAY! .. I think he left it there to troll everyone
My small town I grew up in had a Western Auto, still remember the sign outside. Don't remember much about the inside, but I suppose it was like today's auto stores, except they sold appliances, TV and other assorted electronics. Some Hollywood movies showing a main street usually included a Western Auto sign.
The way that the Line Output Transformer Primary in that Set was constructed was known as Wave Winding.A Lecturer at the College I went to in my youth had come up with a way of curing shorted and hard to get wound components.He would soak them in a mixture of Varnish and Turpentine and then allow them to dry before trying to use them again.I have not tried this myself but he seemed confident that this could be made to work.Good luck with your plan to try to substitute the Line Output Transformer and get a picture on this Set.
I agree, feel the same way, would like to see it work somehow also, Great idea, love your drive and willingness to see this through. Thank you for another Great video, you are Awesome as usual
I like all the great tips on this video. I actually am planning on taking next monday off; or at least half the day to see part 2., I am liking where this is going so far.
I photocopy old schematics as you do to preserve the originals. After I make notes on the photocopies, I scan them for future reference. I love vintage TVs, but restore mostly audio gear.
yeah I've done the exotic car resto.. mice had eaten the wires in a VW convertible but a couple of bags of wiring harness from the junkyard and many splices later I got a 300k+ convertible running again..
You don't fustrate me at all. I love schemas, manuals, phamplets. C&Ds, IPBs. Good to see you can lay your hands on actual paper for a change. Those days are quickly disappearing when buying electronics now days. The pictures of the sets tell all and I enjoy it.
I just love your resurrection videos. Always great commentary, always learn something. Thanks so much for taking what must be a lot of time to produce these and share with others. Long may you continue. The more battered the item, the more intersting the video. Thank you again.
At least there's audio that's a good start. Signs of life irregardless of what's happened to it. That nest is a fire waiting to happen though, at the least I would have pulled it to prevent the set from burning down.
Still a great diagnostic video Shango, thanks for sharing the knowledge! I don't know about So-Cal, but up here at the northern end of the state we did have Western Auto. But that was many moons ago, used to get my bicycle parts there when I was young.
After the intro I swept my mouse over the time line and noticed: no pictures of infomercials or test generators. Oh goodie! Over an hour's worth of electronics troubleshooting with bonus mice nest and silverfish. I gotta sit down for this one. Thanks for a good start to my week :-)

Keep going. This heeeere is one of the best education and entertainment channels in vintage TV out there.
This TV seems to be a lot more work than some of the other ones you've resurrected, I am surprised you're even going to make a part two. Hyped to see if you can get it working again.
Another great diagnosis video, thanks Shango066! I'm looking forward to Part 2, to see if you can cram that NOS Zenith fly in there and get some HV! If it can be done...you're "our guy!"😊
This is my favorite source for fecal-encrusted, insect-riddled electronics repair. I wouldn’t watch silverfish escape scenes anywhere else. Keep up the great work!
Diagnostic thinking, doesn't frustrate me at all. In fact it's through watching your videos and trying to think in a similar way that I've got my old Philips oscilloscope finally working properly. I could've researched, shotgunned all the lockfit transistors and crossed my fingers but as it goes I only had to translate a section of the Dutch service manual, buy a small batch of BF194's and a couple of odd others i had in stock & was away. Much more fun learning how it is supposed to work, why it's not working and what's stopping it from doing than it is just rebuilding something wholesale. Thanks again, and again proud to consider myself a student of your methodology. Also, never knew silverfish ate paper!
42:06 Just an FYI for those learning out there, see that coffee color ring around the mirror like spot of the getter? That is a sign of a tube with a lot of hours on it or been red plated and had a hard life. Still usable, but near its end of life.
My family owned a Western Auto Associate Store in AZ form 1970 through 1986. We recieved our products from the western reigon distribution center in the City of Industry, CA, a suburb of LA, which was closed around 1985.
I love resurrections with flotsam, jetsam and rodent digestive ephemera still in place! Western Auto was a great company who cheaped out on their employees and went out of business. Kind of like the other corporate run stores have all done. 👍😆
I've heard of computer mice, and computer bugs, and wiring described as "a rat's nest", but to actual see evidence of TV mice, and TV bugs, with an actual rat's nest in there is a first :-) Talk about a health hazard :-)
Anyone who has done TV or computer service has a story about the roach-o-matic set. Typically discovered *after* it's been in the shop for a day or two.
Love your long videos, I get to hear your sexy voice more. 🥰 I’m so glad you ain’t giving up on this poor old tv yet. It deserves to be saved by you. 😘💖
I liked the diagnosing of the TV, although, frankly, I would have removed all the crud... ok, granted it adds entertainment value, but yeah... gross. However, the idea of doing a substitution of the flyback by (possibly) a compatible part is an extremely interesting idea. Can't wait to see how it'll turn out. Thanks for sharing a very entertaining and interesting video :)
Many vertebrates (including rats, mice, and even cats) have a "collapsing ribcage". Basically, if they can fit their head through, they can fit their whole body through.
That looks just like a Magnavox portable that my brother's friend had years ago. I never could get the VHF tuner to work; UHF did. Of course I was like 10 years old...
midland were/ are a uk cb and ham radio manufacturer, they have always made solid dependable but boring radios, there saving grace is that they are very modifiable.
Very interesting how the primary of the flyback was wound - would love to have seen how these and some of the more complex IF transformers were made back in the day.
a chassis should not wear a sweater ever really. . . so what's the point in electrifying the poor thing while it's potentially just going to fry tubes that could have been okay sans Mr Rogers snuggling the traces?
Yep I'm just now getting into the video towards the start here when you're looking up the Sam's but I think it's a mouse ate one of the wires inside that's why you got it so it don't work to begin with but you're the pro love your videos I'm glad you're speaking again I hope nobody else pisses you off
When you said you conceded, I thought "Naw, this is a Shango video, he always brings stuff back to life!" Besides, I always thought rat nests improve reception!
I'm glad you decided to talk in this one; it'd been a bitch to follow if silent. Excellent schooling video; will have to archive offline for future reference. Looking forward to part 2.
Of course he wasn't going to give up quite yet. I think the only thing I've seen that he's given up on was that Toshiba amplifier that had a board in it that literally caught fire.
If this replacement tranformer is designed for similar size CRT and tube H-out, it should work OK if the yoke inductance is near the same. I also did it once with old BW TV.
I know the policy about bitching about cleaning the TV, I even held back with the asbestos but christ on a stick that's such a horrific sight! We need a ranked list so this can top it.
